When a smoker inhales smoke from a cigarette CO is absorbed into their blood through their lungs CO is dangerous because it binds to haemoglobin in red blood cells about 200 times more readily than oxygen depriving the body of vital oxygen A It shows the amount of carbon monoxide in a person s breath ppm CO which is a measure of blood carboxyhaemoglobin COHb It also acts as an indicator of the possible level of around 4 000 toxic substances in cigarette smoke 60 of which can cause cancer If a patient gives a reading of 20ppm that of a frequent adult smoker it means that their oxygen carrying capacity is reduced by 5 It also indicates a high level of addiction to nicotine A It takes about 5 6 hours to reduce the original level by half Usually after a maximum period of 48 hours an ex smoker will have the same level of CO as a non smoker in the same environment A After a minimum of 10 minutes A The best time to take a CO reading is as A Parts per million in this case one part of CO in one million parts of air breath This might not seem like very much but ppm has a direct correlation with COHb the percentage of CO combined with haemoglobin in the blood LED Colour Green Yellow 1 Red 2 Reds 3 Reds 4 Reds 4 Reds flashing Description Dangerously addicted smoker late as possible in the day A Clinical research has shown that the popular guidelines are User pr
